Question

Two green plants are kept separately in oxygen-free containers, one in the dark and the other in continuous light. The one in dark will live longer.

• A. True
• B. False

Answer 1

Answer: (B)

Plant exposed to light and dark:

1. Plant kept in continuous light will live longer, because it will be able to produce oxygen required for its respiration by the process of photosynthesis.
2. Plant remaining in the dark will not photosynthesize and hence it will finally die due to no availability of oxygen.
   

Final Answer: The given statement is false.
